SD/SDHC CARD SOUND RECORDER

Updated on 30.6.2015 The PIC16F876A's ADC digitizes the sound and store it in the SD or SDHC card. The firmware works for SD or SDHC cards only, for old SD (before 2009) use ver1 firmware. Do not use SDXC cards with this project because some of them work on 1.8V drive. The code detects whether the card is SD or SDHC and selects the proper addressing system for the card. The PIC's CCP is used as a DAC to con ...

Temperature Recorder using PIC12F683 microcontroller

Description This project uses a MicrochipPIC microcontroller, a serial EEPROM and a thermistor to create a temperature recorder. Performance The temperature is measured and stored at user programmable intervals; this can be from 1 second to 256 seconds. The time interval is set by programming it and the start time into the EEPROM. Most of the time the PIC will be asleep and the EEPROM IC is inactive. This g ...
